Summary: fix for trivial flatten bug in astgen

Initial Comment:
The flatten in compiler.ast (from astgen) doesn't work
for sublists, although the source shows it tries to:

>>> compiler.ast.flatten([1,2,(3,4)])
[1, 2, 3, 4]

>>> compiler.ast.flatten([1,2,[3,4]])
[1, 2, [3, 4]]

The dangers of calling your lists 'list'.. (type is
list check fails.)  A brief glance suggests it gets
called with tuples instead so I don't think the bug has
any obvious consequences.

The patch works but it would be nice if there was a test in
test_compiler.py that checks for correctness of the flattens
too.
